To all whom'it-rrtap cortcrn: l I

ers in which both the hooktlnd bar are cut sheet metal at one operation.

citizen of the United States, 'residihg at Baltimore city, State of Maryland, have invented a new and useful Improvement in Proc' esses of Making Garment-Hooks, of which the following is a specification.

My invention relates to processes 'of making garment-fasteners; and the object is to produce a hook and bar fon'garment-fastenand the latter bent from a single'piece of 'In the manu facture of trousers-waistband hooks and eyes or bars there has been a considerable waste vof sheet metal, owing to the fact that' the hook member is usually of skeleton form, and the; metal cut away to form the hook has gone. to waste. By means of my invention the material which has heretofore been out away to form the skeleton hook is utilized to form-the bar. member or eye for the hook, thus saving both in material and labor in producing garment-fasteners of this character.-

In the accompanying drawings,"Figure 1 is a vertical sectional view through 'dies' for forming thev fasteners' Fig. 2 is a bottom plan view of'the upper die. plan view of the lower die.

7 Fig 4 is a view of the hook-plate.

Fig. 5 is a view of the finished eye or bar, -and Fig. 6 is a view in perspective of the hook member.

Referring-to "Figs." fand 5, the numeral designates a-blan'k cut from sheet metal and provided with rounded ends 2-;and- 3 and shoulders 4 and 5, projecting, laterally from the blank at a-point about central to the blank. Thread-holes 6 6 are formed in the blank near the shoulders. 'In order that the hook'shall be of skeleton form and that the material to be cut away should be utilized to jforrn the bar member, the central -portion is 5 bar 8.

cut out, as shown in Fig. 4, to remove the (Shown in Fig. 5.). The bar 8 is provided with-feet 9, having thread-holes 10.

' In the process of producing my hook and bar the blank shown in Fig. 4' isicut or struck up by a die from a strip or piece of heet metal of the required age, and the bar- Fig. 3 is a topl 8 (shown in Fig. 5) is cut out from within 59 l the blank, andthe feet 9 are bent downward.

Various forms of dies may be employed to perform this process. 1 have. shown in Figs. 1, 2, and 3 one simple forin of dies merely ,to illustrate a means for carrying out the process.v

A is the male die, andB is the female die. The male die is made to conform to the hookyblank at its outer edge a, and the female die has a counterpart recess 6 to receive it and between which and the outer edge a of die A the blank is cut.

The bar-die C is ce'ntrallyformed on the: lower surface of the die A, and its outline conforms to the shape of the hook or bar, as 5 is shown in Fig. 2, and the female die has an aperture 0 formed therein to correspond in shape'with die (Land between the edges of the two the bar or e e blank is out.

A spring-supporte anvil D is fitted to the 79 aperture'o, and its upper surface and the lower surface of die O are fashioned to conform in shape and are'adapted to form'the feet on the ends of thehook or bar.

The tension of springs s is such as to yield readily to the downward pressure of die A and to raisethe anvil as fast as the die A recedes.

upon its upward stroke, so as throw the completed hook or bar out. The relative size-and arrangement of the several parts is such that 30 the anvil is pressed to the bottom of aperture o about as the outer edge of the hook-blank is cut, at which time the bar or eye isbent and fashioned between die 0 and anvil D.

\Punches P P" are employed for forming 5.

the thread-holes,"recessesp 10 being formed to receive them. In this manner the two articles are cut, one from within'the other and one of them'made complete during one stroke of the die-press. It will be obvious that"con- 9 siderable saving of metal results from my processef cutting and stamping up the blank and at the same'time some labor is saved,

since there is but one movement of a die necessary to cut out the'blank to form the hook and both cut and strike up the bar from withinthe body of the hook member. 7 As stated, other machinery might be em ployed and different arrangements of dies used. Those described merely illustrate a possible scheme for carrying out the method.

Having fully described my invention. What I claim as new, and desire tosecure by Letters Patent, is i 1. The herein-described method which consists in cutting two complementary parts from a sheet of material forming a garment hook and bar, the bar member being cut, perforated, bent and completed from wholly witl in the hook member, and the hook member, being cut out and perforated in a single operation forming when cut an article of menu facture substantially complete.

2. The herein-described method which con sists in cutting two complemen tery parts from a. sheet of material, the two parts forming a garment hook andbar, the bar member being cut, perforated, bent and completed from the presence of two witnesses.
